Hagi-yaki tea bowls, a traditional craft of Yamaguchi Prefecture. In the world of tea ceremony, they are highly regarded, being praised as "Ichi-raku, Ni-hagi, San-karatsu" (First Raku, Second Hagi, Third Karatsu). Hagi-yaki is characterized by its soft and warm texture. The pink color seen at the bottom of the vessels is called "Gohon-de," a result of kiln transformation during firing, and is one of the distinctive features of Hagi-yaki. The aging process, known as "Nanabake," where the color changes as tea stains permeate the pottery over time, is also a charming characteristic. These are ceramic yunomi (teacups) with beautiful gradations. Each has a mark on the back. They are new and unused, but have been stored for a long time. - Quantity: Set of 3 - Material: Ceramic, Hagi-yaki - Bottom Shape: Flat bottom - Usage: Yunomi, Tea Ceremony Dimensions: Diameter approx. 9cm, Height approx. 4.5cm The mark is unreadable, but I have determined it to be Hagi-yaki, although it also resembles the characteristics of Asahi-yaki. They are lightweight and easy to hold. Thank you for viewing.
